Meiosis and genetic variation

Front

Which statement is false about INTERPHASE? Cell grows during interphase DNA is replicated during S-phase Interphase only happens in Mitosis and not Meiosis Interphase happens once during Meiosis

Back

Interphase happens once during Meiosis

Front

Which process makes variation / genetic diversity possible?

Back

Meiosis

Front

What is crossing over?

Back

When two homologous chromosomes transfer and exchange genetic information between themselves in Prophase I

Front

How many cycles of Prophase, Metaphase, Anaphase and Telophase occur in Meiosis?

Back

2

Front

Which event during meiosis contributes most to genetic diversity in humans?

Back

Recombination between homologous chromatids during meiosis I

Front

Which of the following correctly describes meiosis?

Back

Meiosis begins with a diploid parent cell and ends with four haploid daughter cells.

Front

If an organism has an N number of 10 chromosomes (haploid # of 10), how many chromosomes are in a somatic cell (body cell) of this organism (what is the diploid #)?

Back

20

Front

Which one of the following is a way that Mitosis is different from Meiosis:

Back

Meiosis results in 4 daughter cells, while Mitosis produces 2 daughter cells. Cells produced by meiosis are all genetically different.

Front

Homologous chromosomes pair up side-by-side in tetrads along the middle of the cell during what kind of cell division?

Back

Meiosis

Front

What is the primary purpose of meiosis in sexually reproducing organisms?

Back

To create gametes with half the number of chromosomes
